joepilot Posted July 23, 2018 Report Share Posted July 23, 2018 Hi, Have a 1994 201J. 1640TT. Electric Globe cowl flap motor removed for overhaul by Allied Motion in AL, I guess. (Was occasionally tripping breaker, now will only run for <1 sec and trips breaker; both directions. Slight burnt elec odor from motor when disassembled. Checked & cleaned connections). Anyway, with the motor out, how much resistance should be on the cowl flap rigging? Maintenance Manual 71-13-02 doesn't mention. Mine seems to have resistance in both directions. Maybe 3-4 pounds worth? I realize air resistance to open flaps is probably more, but just wondering if too much caused motor to wear? BTW, are shops & mechanics everywhere in the country as busy as they are here in SoCal? Wow. Frustrating. Thanks!!! -Joe KCCB Quote Link to comment Share on other sites More sharing options...
carusoam Posted July 23, 2018 Report Share Posted July 23, 2018 Based on manual flaps of an M20C... not much pressure at all when the control is clean and nicely lubricated... Seeing if @M20Doc has an answer... Best regards, -a- Quote Link to comment Share on other sites More sharing options...
joepilot Posted July 23, 2018 Author Report Share Posted July 23, 2018 OK thanks. Cable to indicator in cockpit could need lube, maybe. Quote Link to comment Share on other sites More sharing options...
Guest Posted July 23, 2018 Report Share Posted July 23, 2018 There should be no resistance to movement in the mechanical system. I’d suggest disconnecting a piece at a time until you find the trouble. Clean and lubricate everything. Most shops are busy, there are fewer of us left doing general aviation maintenance.

Vno Posted July 23, 2018 Report Share Posted July 23, 2018 I agree with the above. I have a 92 J and I have the motor out for repair. If you breathe on the cowl flaps they move. Just enough resistance to keep it in place after I let go. Brian Quote Link to comment Share on other sites More sharing options...
